FINANCIAL INFORMATION

Management's Discussion and Analysis

Forward-looking Statements

       This report contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. When used in this report, the words "outlook", "expects," "anticipates," "intends," "plans," "believes," "seeks," "estimates" and similar expressions are generally intended to identify forward looking statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, forward-looking statements are inherently subject to risks and uncertainties, many of which cannot be predicted with accuracy and some of which might not even be anticipated, and future events and actual results, financial and otherwise, could differ materially from those set forth in or contemplated by the forward-looking statements contained elsewhere in this report. We have based these forward-looking statements on current estimates and assumptions made to the best of our knowledge. By their nature, such forward-looking statements involve risks, uncertainties, assumptions and other factors which could cause actual results, including our financial condition and profitability, to differ materially and be more negative than the results expressly or implicitly described in or suggested by these statements. Moreover, forward-looking estimates or predictions derived from third parties' studies or information may prove to be inaccurate. Consequently, we cannot give any assurance regarding the future accuracy of the opinions set forth in this report or the actual occurrence of the developments described herein. In addition, even if our future results meet the expectations expressed here, those results may not be indicative of our performance in future periods.

       These risks, uncertainties, assumptions, and other factors that could cause actual results to differ from our projected results include, among others, the following:

•

changes in governmental and commercial insurer reimbursement for our complete products and services portfolio, including the expanded United States ("U.S.") Medicare reimbursement system for dialysis services;

•

changes in utilization patterns for pharmaceuticals and in our costs of purchasing pharmaceuticals;

•

the outcome of ongoing government and internal investigations;

•

risks relating to compliance with the myriad government regulations applicable to our business including, in the U.S., the Anti-Kickback Statute, the False Claims Act, the Stark Law and the Foreign Corrupt Practices Act, the Food, Drug and Cosmetic Act and comparable regulatory regimes in many of the 120 countries in which we supply dialysis services and / or products;

•

the influence of commercial insurers and managed care organizations;

•

the impact of recently enacted and possible future health care reforms;

•

product liability risks;

•

the outcome of ongoing potentially material litigation;

•

risks relating to the integration of acquisitions and our dependence on additional acquisitions;

•

the impact of currency fluctuations;

•

introduction of generic or new pharmaceuticals that compete with our pharmaceutical products;

•

changes in raw material and energy costs or the ability to procure raw materials; as well as

•

collectability of our receivables due to the financial stability and liquidity of our governmental and commercial payors.

       Important factors that could contribute to such differences are noted in the "Overview" section below, in Note 12 of the Notes to Consolidated Financial Statements (unaudited), "Commitments and Contingencies" included in this report, in Note 20 of the Notes to Consolidated Financial Statements, "Commitments and Contingencies" included in our Annual Report on Form 20-F for the year ended December 31, 2013, and under "Risk Factors" and elsewhere in that report.

       Our business is also subject to other risks and uncertainties that we describe from time to time in our public filings. Developments in any of these areas could cause our results to differ materially from the results that we or others have projected or may project.

       Our reported financial condition and results of operations are sensitive to accounting methods, assumptions and estimates that are the basis of our financial statements. The actual accounting policies, the judgments made in the selection and application of these policies and the sensitivities of reported results to changes in accounting policies, assumptions and estimates, are factors to be considered along with our financial statements and the discussion under "Results of Operations" below. There have been no significant changes during the nine months ended September 30, 2014 to the items disclosed within the critical accounting policies and estimates in Item 5, "Operating and Financial Review and Prospects – Critical Accounting Policies" in our Annual Report on Form 20-F for the year ended December 31, 2013.

Financial Condition and Results of Operations

       You should read the following discussion and analysis of the results of operations of Fresenius Medical Care AG & Co. KGaA ("FMC-AG & Co. KGaA," or the "Company") and its subsidiaries in conjunction with our unaudited consolidated financial statements and related notes contained elsewhere in this report and our disclosures and discussions in our Annual Report on Form 20-F for the year ended December 31, 2013. The results within this discussion and analysis are unaudited. In this report, "FMC-AG & Co. KGaA," or the "Company," "we," "us" or "our" refers to the Company or the Company and its subsidiaries on a consolidated basis, as the context requires. The term "North America Segment" refers to our North America operating segment and the term "International Segment" refers to the combination of our "EMEALA" (Europe, Middle East, Africa, and Latin America) operating segment and our Asia-Pacific operating segment. The term "Constant Currency" or at "Constant Exchange Rates" means that we have translated local currency revenues for the current reporting period into U.S. dollars using the same average foreign currency exchange rates for the conversion of revenues into U.S. dollars that we used to translate local currency revenues for the comparable reporting period of the prior year.

Overview

       We operate in both the field of dialysis care and the field of dialysis products for the treatment of end-stage renal disease ("ESRD"). Our dialysis care business, in addition to providing dialysis treatments to patients with ESRD, includes pharmacy services, vascular access surgery services, laboratory testing services, physician services, hospitalist services, health plan services and urgent care services (together, "Care Coordination"). Our dialysis products business includes manufacturing and distributing products for the treatment of ESRD. In the U.S., the Company also provides inpatient dialysis services as well as other services under contract to hospitals. We estimate that providing dialysis and distributing dialysis products

represents a worldwide market of approximately $75 billion with expected annual worldwide market growth of approximately 4 percent, adjusted for currency. Patient growth results from factors such as the aging population and increased life expectancies; shortage of donor organs for kidney transplants; increasing incidence of kidney disease and better treatment of and survival of patients with diabetes and hypertension, which frequently precede the onset of chronic kidney disease; improvements in treatment quality, which prolong patient life; and improving standards of living in developing countries, which make life-saving dialysis treatment available. Key to continued growth in revenue is our ability to attract new patients in order to increase the number of treatments performed each year. For that reason, we believe the number of treatments performed each year is a strong indicator of continued revenue growth and success.

       In addition, the reimbursement and ancillary services utilization environment significantly influences our business. The majority of treatments are paid for by governmental institutions such as the Centers for Medicare & Medicaid Services ("CMS") in the United States. As a consequence of the pressure to decrease health care costs, government reimbursement rate increases have been historically and are expected in the future to be limited. While we have generally experienced stable reimbursement globally, including the balancing of unfavorable reimbursement changes in certain countries with favorable changes in other countries, the stability of reimbursement in the U.S. has been affected by (i) the implementation of the ESRD prospective payment system ("ESRD PPS") in the U.S. in January 2011, (ii) the U.S. federal government across the board spending cuts in payments to Medicare providers commonly referred to as U.S. Sequestration (as defined below), (iii) commencing on January 1, 2014, the reduction to the ESRD PPS rate to account for the decline in utilization of certain drugs and biologicals associated with dialysis (see discussion of the American Taxpayer Relief Act of 2012 ("ATRA") below) and (iv) the enactment of the Protecting Access to Medicare Act of 2014 ("PAMA") (see discussion of PAMA below). In the future we expect to experience generally stable reimbursements for dialysis services globally.

       With the enactment in the U.S. of the Medicare Improvements for Patients and Providers Act of 2008 ("MIPPA"), Congress created the ESRD PPS pursuant to which CMS reimburses dialysis facilities with a single payment for each dialysis treatment, inclusive of (i) all items and services included in the pre-2011 ESRD composite rate, (ii) oral vitamin D analogues, oral levocarnitine (an amino acid derivative) and all erythropoietin stimulating agents ("ESAs") and other pharmaceuticals (other than vaccines and certain other oral drugs) furnished to ESRD patients that were previously reimbursed separately under Part B of the Medicare program, (iii) most diagnostic laboratory tests and (iv) certain other items and services furnished to individuals for the treatment of ESRD. The base ESRD PPS payment is subject to case mix adjustments that take into account individual patient characteristics (e.g., age, body surface area, body mass, time on dialysis) and certain co-morbidities. The base payment is also adjusted for (i) certain high cost patient outliers due to unusual variations in medically necessary care, (ii) disparately high costs incurred by low volume facilities relative to other facilities, (iii) provision of home dialysis training and (iv) wage-related costs in the geographic area in which the provider is located.

       The ESRD PPS payment amount is also subject to annual adjustment based on increases in the costs of a "market basket" of certain healthcare items and services less a productivity adjustment.

       In addition to creating the ESRD PPS, MIPPA also created the ESRD quality incentive program ("QIP") which began affecting payments starting January 1, 2012. Dialysis facilities that fail to achieve quality standards established by CMS could have payments reduced by up to 2 percent. Performance on specified measures in a fiscal year affects payments two fiscal years later. For instance, the payments we receive during 2014 will be affected by our performance measures from 2012. Based on our performance from 2010 through 2012, the QIP's impact on our results through 2014 is immaterial. The initial QIP measures for 2010 and 2011 focused on anemia management (measured by hemoglobin level) and dialysis

adequacy (measured by Urea Reduction Ratio or URR). For payment year 2014, CMS adopted four additional measures: prevalence of catheter and A/V fistula use, reporting of infections to the Centers for Disease Control and Prevention, administration of patient satisfaction surveys and monthly monitoring of phosphorus and calcium levels. For payment year 2015, CMS will continue all of the 2014 QIP measures except URR dialysis adequacy, expand the scope of infection reporting and mineral metabolism reporting, and add four new measures. Payment year 2015 added measures consist of three new clinical measures (hemodialysis adequacy for adult patients, hemodialysis adequacy for pediatric patients and peritoneal dialysis adequacy for adult patients), and one new reporting measure (anemia management reporting). For payment year 2016, CMS will continue all of the 2015 QIP measures and add two new clinical measures (proportion of patients with hypercalcemia and dialysis-related infections reported to the Center for Disease Control and Prevention's National Health Safety Network by ESRD facilities treating patients on an in-center basis). For payment year 2017, CMS will continue ten of the eleven 2016 QIP measures (a total of 7 clinical measures and 3 reporting measures), remove the anemia management clinical measure (hemoglobin greater than 12 g/dL), revise the patient satisfaction survey reporting measure, and adopt one new clinical measure that addresses care coordination (measured by a Standardized Readmission Ratio or SRR). For payment year 2018, CMS will continue all of the measures proposed for payment year 2017 (with the exception of changing the patient satisfaction survey to a clinical measure), and to add five new measures consisting of two clinical measures (evaluating transfusions in the ESRD population as measured by a Standardized Transfusion Ratio or STrR and pediatric peritoneal dialysis adequacy) and three reporting measures (pain assessment, clinical depression screening, and healthcare personnel influenza vaccinations).

       The Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010 (collectively, "ACA") implements broad healthcare system reforms, including (i) provisions to facilitate access to affordable health insurance for all Americans, (ii) expansion of the Medicaid program, (iii) an industry fee on pharmaceutical companies that began in 2011 based on sales of brand name pharmaceuticals to government healthcare programs, (iv) a 2.3 percent excise tax on manufacturers' medical device sales starting in 2013, (v) increases in Medicaid prescription drug rebates effective January 1, 2010, (vi) commercial insurance market reforms that protect consumers, such as bans on lifetime and annual limits, coverage of pre-existing conditions, limits on administrative costs, and limits on waiting periods, (vii) provisions encouraging integrated care, efficiency and coordination among providers and (viii) provisions for reduction of healthcare program waste and fraud. ACA does not modify the dialysis reimbursement provisions of MIPPA, except to change the annual update provision by substituting a productivity adjustment to the market basket rate of increase for a MIPPA provision that specified a one percentage point reduction in the market basket rate of increase.

       On August 2, 2011, the Budget Control Act ("BCA") was enacted, raising the U.S. debt ceiling and putting into effect a series of actions for deficit reduction. Pursuant to the BCA, automatic across-the-board spending cuts over nine fiscal years (2013-2021), projected to total $1.2 trillion for all U.S. Federal government programs required under the BCA became effective as of March 1, 2013 and were implemented on April 1, 2013 for CMS reimbursement to providers. The Bipartisan Budget Act of 2013 extended the cuts to mandatory spending programs such as Medicare for an additional two years. The reduction in Medicare payments to providers and suppliers is limited to one adjustment of no more than 2 percent through 2022 (the "U.S. Sequestration"), rising to 2.9 percent for the first half of FY 2023 and dropping to 1.11 percent for the second half of FY 2023. Pursuant to PAMA, the reductions pursuant to U.S. Sequestration for the first six months of 2024 will be 4 percent, and there will be no reductions for the second six months of 2024. The Medicare sequestration reimbursement reduction is independent of annual inflation update mechanisms, such as the market basket update pursuant to the ESRD PPS.

       The impact of the U.S. Sequestration on our dialysis care revenues from Medicare, beginning in the second quarter of 2013, resulted in a decrease of approximately $18 million in operating income for the nine months ended September 30, 2014 driven by the absence of U.S. Sequestration in the first quarter of 2013. The impact of the U.S. Sequestration for the last twelve months has resulted in an aggregate reduction to our operating income of $74 million.

       ATRA directed CMS to reduce the ESRD PPS payment rate, effective January 1, 2014, to account for changes in the utilization of certain drugs and biologicals that are included in the ESRD PPS. In making such reduction, the law requires CMS to use the most recently available pricing data for such drugs and biologicals. On November 22, 2013, CMS issued the final rule regarding the 2014 ESRD PPS rate. The base rate per treatment was reduced from $240.36 to $239.02 for 2014. This change reflected (a) a bundled market basket increase of 3.2 percent, reduced by an estimated multifactor productivity adjustment of 0.4 percent; (b) the application of a wage index budget neutrality factor and a home dialysis training add-on budget neutrality factor; and (c) the application of a portion of an overall reduction in the base rate ($8.16 per treatment) to account for a decrease in the historical utilization of certain ESRD-related drugs and biologicals from 2007 to 2012. As set forth in the November 2013 final rule, CMS will phase in the drug utilization adjustment mandated by ATRA, which CMS estimates will total $29.93 per treatment, over three to four years. CMS intended that the portion of the reduction that will be applied in 2014 and 2015 will largely offset the net market basket increases in average payments to ESRD facilities as a whole resulting in essentially unchanged reimbursement rates from 2013 to 2015. CMS stated that it would consider in 2015 whether to apply the remainder of the $29.93 reduction in 2016 alone or spread it out over 2016 and 2017.

       On April 1, 2014, PAMA was signed into law. This law modifies ATRA such that dialysis reimbursement for 2015 is intended to equal that for 2014. In addition, the reimbursement reductions mandated by ATRA for 2016 and 2017 have been eliminated. Instead, the market basket updates net of the productivity adjustment for each of 2016 and 2017 have been reinstated, though they will be reduced by 1.25 percent each year. For 2018, the market basket update net of the productivity adjustment will be reduced by 1 percent. In addition, the law mandates that ESRD-related drugs with only an oral form, including our phosphate binder PhosLo®, are excluded from the ESRD PPS and separately reimbursed until 2024. Finally, under the law, the reductions pursuant to U.S. Sequestration for the first six months of 2024 will be 4 percent, and there will be no reductions for the second six months of 2024.

       On October 31, 2014, CMS issued the final rule updating Medicare payment policies and rates under the ESRD PPS for dialysis services provided on or after January 1, 2015. For calendar year 2015, CMS increases the ESRD PPS base rate to $239.43. Following the requirements of PAMA, this amount reflects elimination of the drug utilization adjustment, the application of a 0.0 percent market basket update net of the productivity adjustment, and the application of the proposed wage index budget-neutrality adjustment factor.

       Any significant decreases in Medicare reimbursement rates could have material adverse effects on our provider business and, because the demand for dialysis products is affected by Medicare reimbursement, on our products business. To the extent that increases in operating costs that are affected by inflation, such as labor and supply costs, are not fully reflected in a compensating increase in reimbursement rates, our business and results of operations may be adversely affected.

       On February 4, 2013, CMS announced plans to test a new Comprehensive ESRD Care Program and issued a solicitation for applications. CMS stated that it sought to work with up to 15 healthcare provider groups comprised of dialysis clinics and nephrologists, also known as ESRD Seamless Care Organizations

("ESCOs"), to test a new system of payment and care delivery that seeks to deliver better health outcomes for ESRD patients while potentially lowering CMS's costs. ESCOs that achieve the program's minimum quality thresholds and generate reductions in CMS's cost of care above certain thresholds for the ESRD patients covered by the ESCO will receive a share of the cost savings. ESCOs that include dialysis chains with more than 200 facilities are required to share in the risk of cost increases and reimburse CMS a share of any such increases. Organizations must apply and be approved by CMS to participate in the program. In August 2013, we submitted an application to participate in the program as an ESCO. Following submission of our application, CMS announced that it would suspend review of all applications and reopen its request for application in the winter of 2014 to solicit additional participation.

       Following receipt of stakeholder feedback, CMS issued revised specifications for the Comprehensive ESRD Care Program in March of 2014. Under the revised specifications, large dialysis organizations were required to submit non-binding applications on or before June 23, 2014, while small dialysis organizations have until September 2014 to apply. We submitted non-binding applications for several different markets across the United States which CMS is currently reviewing. CMS is expected to make a determination on applications from large dialysis organizations in the coming months. Once an ESCO application is approved, CMS and the prospective ESCO will share data and enter into negotiations on the final terms of the shared savings arrangement. Should an agreement be executed, CMS intends that the ESCO will go into effect in January 2015.

       The Bundled Payments for Care Improvement initiative (BPCI) is a CMS three year pilot initiative with bundled payments for the individual services furnished to Medicare beneficiaries during a single episode of illness or course of treatment, including acute inpatient hospital services, physician services, and post-acute services. On January 31, 2013, CMS announced the health care organizations selected to participate in BPCI, which include our subsidiary, Sound Inpatient Physicians, Inc. Sound Physicians is currently planning and preparing to commence participation under BPCI in 2015 in several markets.

       Fresenius Medical Care Holdings, Inc. ("FMCH") has an Epogen supply agreement with Amgen which expires at the end of this year. FMCH is engaged in negotiations to renew this agreement and expects to execute a new multi-year ESA supply agreement with Amgen prior to the expiration of the current agreement. Any failure to reach an agreement that gives FMCH continued access to Amgen ESAs at reasonable pricing could have a material adverse impact on our results of operations.

       We have identified three operating segments, North America Segment, EMEALA, and Asia-Pacific, which were determined based upon how we manage our businesses. All segments are primarily engaged in providing dialysis care services and distributing products and equipment for the treatment of ESRD. For reporting purposes, we have aggregated the EMEALA and Asia-Pacific operating segments as the "International Segment." We aggregated these operating segments due to their similar economic characteristics. These characteristics include same services provided and same products sold, the same type of patient population, similar methods of distribution of products and services and similar economic environments. Our General Partner's management board member responsible for the profitability and cash flow of each segment's various businesses supervises the management of each operating segment. The accounting policies of the segments are the same as those we apply in preparing our consolidated financial statements using accounting principles generally accepted in the United States of America ("U.S. GAAP").

       Our management evaluates each segment using measures that reflect all of the segment's controllable revenues and expenses. With respect to the performance of business operations, our management believes that the most appropriate U.S. GAAP measures are revenue, operating income and operating income

margin. We do not include income taxes as we believe this is outside the segments' control. Financing is a corporate function which our segments do not control. Therefore, we do not include interest expense relating to financing as a segment measurement. Similarly, we do not allocate certain costs which relate primarily to certain headquarters overhead charges, including accounting and finance, etc. ("Corporate"), because we believe that these costs are also not within the control of the individual segments. Production of products, production asset management, quality management and procurement are centrally managed at Corporate by Global Manufacturing Operations. The Company's global research and development is also centrally managed at Corporate. These Corporate activities do not fulfill the definition of a segment. Products are transferred to the segments at cost; therefore no internal profit is generated. The associated internal revenues for the product transfers and their elimination are recorded as Corporate activities (See Note 15 of the Notes to Consolidated Financial Statements (unaudited) "Segment and Corporate Information" found elsewhere in this report). Capital expenditures for production are based on the expected demand of the segments and consolidated profitability considerations. In addition, certain revenues, investments and intangible assets, as well as any related expenses, are not allocated to a segment but accounted for as Corporate. Accordingly, all of these items are excluded from our analysis of segment results and are discussed below in our consolidated results of operations.
